Description Prakash P. 2025-08-29 10:11:18 UTC

I have a partition configured as automount with systemd. In the monitor widget for disk usage I get a default sensor for this partition monitoring used space. After configuring the sensor it works well, but as soon as I reboot, it vanishes. I doesn't automatically appear when I access the partition and thus it gets (auto)mounted. Once I enter the configuration dialog (maybe twice) the sensor is shown as configured again. I am on Arch Linux.

This is an issue in udisks. We have a similar issue in KDE Linux with our Btrfs sub-volumes; see invent.kde.org/kde-linux/kde-linux/-/issues/297.

Please feel free to report the issue at https://github.com/storaged-project/udisks/issues, and then link it here. Thanks a lot!
